Official description

The Product Feed Manager for WooCommerce – CTX Feed – Support 220+ Shopping, AI & Social Channels plugin for WordPress is vulnerable to PHP Code Injection in all versions up to, and including, 8.0.26. This is due to insufficient sanitization of the `feedConfigCustom2` parameter — only `wp_unslash()` is applied before the value is stored verbatim via `update_option()`, and during feed generation the `Custom2Template::evaluate_return()` method passes the stored `{(return ...)}` template expressions directly to PHP's `eval()` function without any code-level sanitization. This makes it possible for authenticated attackers, with Shop Manager-level access and above, to inject and execute arbitrary PHP code on the server, escalating their privileges beyond what the role normally permits to full remote code execution and site takeover. The `ctxfeed_custom2_eval_enabled` option defaults to `true`, meaning no additional administrator configuration is required for this attack path to be exploitable out of the box.

The underlying weakness: Improper Control of Generation of Code

The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment.

How developers prevent this class of flaw

  • Refactor your program so that you do not have to dynamically generate code.
  • Run your code in a jail or similar sandbox environment that enforces strict boundaries between the process and the operating system. This may effectively restrict which code can be executed by your product. Examples include the Unix chroot jail and AppArmor. In general, managed code may provide some protection. This may not be a feasible solution, and it only limits the impact to the operating system; the rest of your application may still be subject to compromise. Be careful to avoid CWE-243 and other weaknesses related to jails.
  • Use dynamic tools and techniques that interact with the product using large test suites with many diverse inputs, such as fuzz testing (fuzzing), robustness testing, and fault injection. The product's operation may slow down, but it should not become unstable, crash, or generate incorrect results.
